The extension of EAT's E-Glo range of valve phono stages into something bigger was inevitable, but not hurried – enter EAT's first integrated all-tube amplifier, the E-Glo i
Regular readers will already know that I use two of EAT's cartridges [HFN Dec '18 and '19], two of its phono stages [HFN Mar '17 and Feb '19] and a B-Sharp turntable [HFN Jul '20]. The E-Glo i is thus among family members and there's every chance I was going to be predisposed…
This month we review and test releases from: San Francisco Symphony/Michael Tilson Thomas, Gidon Nunes Vaz Quartet, Vov Dylan & Glenn Amer, Hallé Orch/Sir John Barbirolli and Jonas Kaufmann.
The Colorado company celebrates its platinum anniversary with a reworked version of a fully balanced integrated that sent the preamp stage packing. Another class act?
Back in 1993, Charles Hansen – the designer and founder of respected US loudspeaker specialist Avalon Acoustics – formed Ayre Acoustics. Over the 25 years that followed, he built up the brand, adding a range of innovative preamps, power amplifiers and integrated designs, all descended from the company's original 'zero-negative feedback' V-1 power amplifier. Bolstering the current lineup are various digital sources, such as the Ayre QX-5 Twenty USB/streaming DAC [HFN Dec '17], phono stages, and head-fi products like the Codex DAC/headphone preamp [HFN Jul '16] – all at prices that indicate they're not aimed at the mass market.
Packed with proprietary technology, this network bridge is the obvious partner for Aqua's own DACs. But does its appeal extend beyond a one-brand digital set-up?
Never let it be said that AQ Technologies is either a follower of fashion or a taker of the easy route: the Milan-based company behind the Aqua range always does things its own way. And while that might sometimes seem like an exercise in making life difficult for itself, the policy typically pays off in the performance, as we discovered when reviewing the Aqua Formula xHD Optologic DAC [HFN Apr '20]. Under the Nextel-finished anti-resonant aluminium casework of that model – one of three DACs in a total Aqua lineup of five products – is a galvanically-isolated resistor-ladder converter of novel design.
While a near dead-ringer for the amp it replaced, this '60s integrated saw Leak leverage new technology to boost performance and widen its appeal. How does it sound today?
It's not unusual for a successful hi-fi product to be updated with mild revisions during its lifetime. Often the changes are minimal: a tidied-up fascia to match a new model added elsewhere in the range, or an extra function or minor circuit redesign. This was certainly not the case with the Leak Stereo 30 Plus amplifier of 1969, which replaced the Stereo 30 [HFN Oct '10] first seen in 1963. Side by side the two looked much the same, but inside the 30 Plus was all new in order to take advantage of improved technology.
